Hi, Adrian,

I have raised a bug report internally to address the problem of the documentation describing the PRE_TARGET and 
POST_TARGET in the same terms as the other variables/macros.

I think it makes sense that PRE_TARGET and POST_TARGET should reference targets, because that is the surest way to 
arrange for pre-stuff to be done absolutely before everything else and post-stuff absolutely after everything else.  
Otherwise, it's rather convenient to be able to do something like:

define POST_BUILD
$(RM_HOST) $(HOME)/bin/$@
$(CP_HOST) $@ $(HOME)/bin
enddef

(for lack of a better example).  Some of these macros can even make use of the special make variables, like $@ above.

PRE_BUILD may be able to substitute for PRE_TARGET if its actions can be performed after ensuring the dependencies of 
your build target, but as you're invoking SVN actions I doubt that this would work for you.

Apart from that, I can't imagine why adding a redundant POST_CLEAN macro should make the PRE_TARGET work.  Could you 
provide a sample project that demonstrates the problem?

Cheers,

Christian

	On a related note, it is confusing that the two macros I'm using, PRE_TARGET and 
	POST_CLEAN require different syntax.
	Further to that, there is no mention of the required syntax in http://www.qnx.com/developers/docs/6.4.1/neutrino/prog/
make_convent.html
	
	I have found (by trial and error) that the following works:
	
	PRE_TARGET=DO_SOMETHING
	DO_SOMETHING :
		$(TOUCH_HOST) $(PROJECT_ROOT)/did.something.txt
	
	POST_CLEAN=$(TOUCH_HOST) $(PROJECT_ROOT)/did.something.txt
	
	
	So the PRE_TARGET requires a new target, whereas the POST_CLEAN requires commands directly.
	
	A note for each macro in the help could help others in the future.
	Even better would be to pick one method (I prefer a list of targets) and use it consistently for these macros.
